Question about choice of optics?

on the sportlines anyway, all mia do/did was drill a hole in the cylinder:mad:
i doubt its good for the piston o-ring to be running over a rough hole a lot

Maybe... but depends on the type of drill bit used

se conman

Regardless of what drill bit is used , or how well the burr is removed after drilling , a compressed o-ring expanding into a hole and then being pushed/pulled across the edges of the hole will always/eventually degrade.

That happens in most cylinders anyway.

Regarding the hole in the cylinder... A POS (piece of ****) M4 arrived on my desk around halloween. I was told I could skirmish her. So... I take her to GTAC 2 for Zombie Rec. It chronos at 133 fps. The reason? The gearbox, gears, cylinder, piston and practically the whole thing is plastic. And the cylinder has a big HUGE hole in it. I taped the hole after noticing my range was perhaps ten feet, got better range but it is very variable. Then I saw paint INSIDE the barrel... Broken motor housing...

Might want to split this thread into a "Methods of Downgrading" one too.
'Cos none of this has anything to do with the original topic.

Yeah I don't want to see this turning into another petty argument.

Anywho I bought myself an Eotech of Ehobby in the mean time thanks for the info folks.

Which one? Let us know how you find it when it arrives!

Do tell me what happens in a normal vented cylinder?

Doesnt the piston head and o ring pass a rather large hole?



And nobody said it was a good or bad idea

Phractal

Fleck, do tell how it goes. How much it costin? And the drill bit will Still make a hole, which will Still do damage to those O rings. Just use a lower velocity spring

Will do lads! Have customs in the back of my mind though, I dont think they like their Eotech's!

It was this one

Flecktarn

Well I overcome with shock and glee. The Eotech arrived today, serious service from Ehobbyasia! Got the Eotech and a screen protecter for the grand total of €57.99 and arrived from HK in 2 days! Am very impressed with the sight itself, a small bit of ghosting but a big step-up from a normal red dot.

Anyone know how to attach the plastic things that cover the lenses, I got one with the Eotech?

If it's a clear thing with three prongs, it's installed by shoving. Try not to get fingerprints on the inside while doing so because you won't be able to wipe in there. Worth removing the battery housing before going at it, because the arm can get in the way.

If it's a flip-up front and back thing, hold it in your good throwing hand and throw it in the bin. If you want to know why, you need to unscrew the cowling on the sight with an allen key, fit the cover into it, get it back in position and screw it on again - needs an allen key. Use it for a while and soon you'll be unscrewing and winding up for a good hard throw.

Yeah I have that thing on already.

Ah I see thanks, like in this picture yeah. I not gonna throw it away just yet, I think it serves a bit of purpose.

Thanks for the help man.

The problem I had with it was it getting knocked closed whenever I'd let my gun hang by its sling (or get knocked by a twig, and sometimes jostled at all). You don't notice, until you bring it up to your eye (which is because you need it RIGHT THE HELL NOW) and it's all dark. I'd installed it so's I could close off the sight for close-quarters stuff because I'd had an EOTech replica smashed in The Warehouse, but frankly I'd rather just take it off than have to put up with that damn thing anymore.

Phractal

Hmmm that EoTech looks to be my next purchase! Surely it will look awesome on the G36c while serving a very good purpose and TWO DAYS? Beautiful shipping time!

i probaly sound like a complete dope but wwhat does ghosting i always see it mentioned and i've never asked

evilrobotshane

It's an effect where a faded version of the crosshair or what have you is visible near the proper one, which tends to make a blurry annoying mess that's hard to figure out where the real centre is. At a guess I'd say it's caused by cheap optics causing the thinger to project on both surfaces of the lens, with a bit of refraction going on in the middle. But I don't know nothing about optics. All you need to know is that it sucks, and with that description you'll recognise it when you see it.

What would be a decent 4x ACOG be as opposed to the red dot "ACOG".

The amount of branded and cheapo Chinese ones has me a bit confuddled.

this one is very good 4x32 red/green cross sight http://www.actionsportgames.com/es/product/product.asp?productid=377098&visible=2#
